Abstract

The application of a neural network controller is described. Three learning algorithms for online implementation of the controller are discussed. These control schemes do not require any information about the system dynamics except an upper bound of the inertia terms. Selection of the number of layers in the neural network, the number of neurons in the hidden layer, initial weights for the network, and the critic coefficient was done based on the results of preliminary tests. The performances of the three learning algorithms were compared. The effectiveness of the neural net controller in handling time-varying parameters and random noise was tested by a case study on a remotely operated vehicle (ROV) system for robotic underwater operations. The results of the comparisons and the testing are presented in detail.<>

遥控车辆智能控制系统的设计
介绍了神经网络控制器的应用。讨论了控制器在线实现的三种学习算法。这些控制方案不需要任何关于系统动力学的信息,除了惯性项的上界。在初步测试结果的基础上,选择神经网络的层数、隐藏层的神经元数、网络的初始权值和批判系数。比较了三种学习算法的性能。以水下机器人遥控操作系统为例,验证了神经网络控制器在处理时变参数和随机噪声方面的有效性。详细地介绍了比较和测试的结果
